libcamera: controls: Reorder and update description of existing controls
Group AE, AWB, etc. controls together for accessibility.
Update descriptions for Contrast, Brightness, and Saturation controls.
Update the uvcvideo and vimc pipeline handlers to use the new
brightness, contrast and saturation units. UVC has no explicit units for
those controls, so map them with a best effort heuristic. For VIMC,
hardcode the control range based on knowledge of the driver
implementation for simplicity.
